A bone fragment has lost 75% of its original carbon-14. What is the age of the bone fragment? My answer is about 11 000 years but I don't know if its right

Suppose that the point (rho, theta, phi)= (12, 2pi/3, 5pi/4) in spherical coordinates can be expressed as (x, y, z) in rectangular coordinates. Find x+z. I first found x by using the conversion method (r*sin(theta)cos(phi)= x ) I got -3(sqrt(6)). Then I f...

The graph of 4/(2-cos(theta)) forms a closed curve. The area of the region inside the curve can be expressed in the form k \pi. What is k^2? So I tried this problem and I got it to be an ellipse 1 = (((x + 8/6)^2)/((16/3)^2)) + ((y^2)/4)) Is this correct?

Let S be the set of points {(r, theta): 2<=r<=6, pi/3 <= theta<= 5pi/6} Find the area of S. Im having trouble with this problem and have been stuck on it for a while. Any help?

Let a and b be real numbers. The complex number 4 - 5i is a root of the quadratic z^2 + (a + 8i) z + (-39 + bi) = 0. What is the other root? I tried working this problem and so far I got that (a+8i) - (4-5i)= (-39-bi)/(4-5i). Im not sure how to solve this...

Find the complex number z that satisfies (1 + i)z - 2 overline{z} = -11 + 25i. Im not sure how to solve this. I tried distributing the z out first but im still confused on this problem.

The system of equations |z - 2 - 2i| = \sqrt{23}, |z - 8 - 5i| = \sqrt{38} has two solutions z1 and z2 in complex numbers. Find (z1 + z2)/2. Im really just plain old confused. Could anyone help me out?

Let z and w be complex numbers such that |2z - w| = 25, |z + 2w| = 5, and |z + w| = 2. Find |z|. I need a little help with absolute values on complex numbers.
